Temporarily disabling DiskSuite mirroring?

Temporarily disabling DiskSuite mirroring?

Post by Be » Thu, 27 Sep 2001 22:57:13



I am running a backup procedure that runs several checks on a disk.
However if the disk is mirrored the checks will fail and the backup
bombs out. Is there anyway to disable the mirroring temporarily to run
the backup? My thought was to revert to the original vfstab and remove
the "set md" line from the /etc/system file. Am I forgetting
something?

Thanks in advance.

So fix your backup procedure, because that's broken.

I'm not going to give any suggestions on how to disable mirrors because
then I'd be encouraging you to go down the wrong path.

It's perhaps a better idea to use fssnap when doing backups, see
http://www.sun.com.au/news/onsun/2001-04/hot_tips.html

However, if you want to unmirror the disk temporarily, you could just
metadetach the mirror, but I suspect your script might fail even if it's a
one way mirror.

Turning off all the metadevices via /etc/vfstab and /etc/system sounds a bit
drastic just to check disks and do a backup, mind you.

1. Disabling screensaver temporarily

Hi all,

how can I disable the screensaver temporarily (e.g. in a shell script) for
watching TV or a DVD under KDE 2.1.2 without the screensaver locking the
screen. I have tried the command

"dcop kdesktop KScreensaverIface enable false"

but it does not work. I get the error message "no such function". Please
help.

Is there documentation of the supplied interface available?

Regards
Detlev
